In a sub - stage lunch of a satellite, the first stage brings the satellite to a height of 150 km and the second stage gives it the necessary critical speed to put . It in a circular orbit around the Earth , which stage requires more expenditure of fuel ? (Given , M_(E)=6.0xx10^(24)kg,R=6.4xx10^(6)m,G-6.67xx10^(-11)Nm^(2)kg^(-2)).

In a two stage launch of a satllite, the first stage bringe the satlilte to a height of 500 km and the second stage given it the necessary critical speed to put it in circular orbit around the Earth. Which stage requires more expenditude of fuel? (Neglect damping due to air resistance, especially in the first stage). Mass of the Earth = 6.0 xx 10^(24) kg ,radius of Earth = 6400 km, G = 6.67 xx 10^(-11) Nm^(2) kg^(-2) .

Find the ratio of the orbital speeds to two satellites of the earth if the satellites are at height 6400km and 19200km. (Radius of the earth = 6400km.)

Find the ratio of the orbital speeds of two satellites of the earth if the satellites are at height 6400 km and 19200 km. (Radius of the earth = 6400 km).

A satellite of mass 250 kg is orbiting the earth at a height of 500 km above the surface of the earth. How much energy must be expended to rocket the satellite out of the gravitational influence of the earth? Mass of earth = 6 xx 10^24 kg Radius of earth = 6400km.
